It is a fishing line which is made up of artificial substances, including nylon, polyethylene, Dacron and Dyneema. With the help of this wire, the dense square net is made. Square net is produced where the hair is being knotted. When 1 to 2 hair is knot in the net then its knotting is invisible and when 4 to 6 hair comes together to make a knot then it is visible like a pen dot point. Single hair knot is good for visibility for skinny effect but bad for life. Single hair knot hair patch life is 5 to 6 months. Where as quad hair knot is not good for visibility but great for life span. Quad plus knot hair patch life is one to one and half years.
